Advanced DAX Training: Understand and Optimize Power BI Data Models (ADAX)


Course Overview

DAX language was created specifically for the handling of data models, through the use of formulas and expressions. DAX is used in several Microsoft Products such as Microsoft Power BI, Microsoft Analysis Services and Microsoft Power Pivot for Excel. These products all share the same internal engine, called Tabular/Vertipaq (xVelocity before). With DAX we have the ability to include business logic in calculations in order to enrich our business intelligence models.

Who should attend

This course is intended for the novice as well as experienced business and data analysts who have prior experience using DAX and are looking deeper knowledge about the language and how to test, and improve the performance the model.


Before attending this course, it is recommended that students have the following skills:

  • Desire to learn more about DAX
  • Prior exposure to the DAX calculations is recommended.
  • Understanding of dimensional modelling is recommended.
  • Knowledge about any functional programming language is recommended, but not necessary

Course Objectives

The objective of the course content is to acquire advanced knowledge about DAX in order to develop using good practices.

  • In the course the main concepts and the most used functions are reviewed.
  • The different techniques and tools to debug and optimize DAX code are also shown.
  • Labs use a variety of close-to-real life problems to provide a broad lab experience using DAX language
Upon completion of this course, the student will be able to:
  • Understand the key functions in DAX
  • Understand the different elements that can be created with DAX
  • Understand the different context involve in DAX
  • Perform a variety of query’s using DAX
  • Debug DAX
  • Optimize DAX
